Dyson-Schwinger approach to pion-nucleon scattering using time-ordered perturbation theory

B. Blankleider, J. L. Wray, A. N. Kvinikhidze

We present a simple description of pion-nucleon ($\pi N$) scattering taking into account the full complexity of pion absorption and creation on the nucleon. To do this we solve Dyson-…
